Improved disposable applicator for topical composition

a disposable applicator and composition technology, applied in the field of single-use disposable applicators, can solve the problems of user or patient being exposed to broken glass, less options available, and fewer options, and achieve the effect of reducing the risk of use or patient exposure to broken glass, reducing the risk of contact with broken glass, and reducing the risk of use or patient exposur

Problems solved by technology

Where application or spreading of the liquid is also required, there are fewer options available, such as fragile breakage of a glass container inside an applicator, or mechanical piercing of a film of foil seal to release the contained fluid.
In the first case, such as in the DERMABOND™ applicator, the breakage of a glass ampoule poses a risk of use or patient exposure to broken glass.
Piercing a film or foil requires a mechanism such as a screw or pin, and most designs require use of two hands or a seal that can leak and spill the enclosed liquid.
One newer design uses a built in weakness in a sealed tube whi

Embodiment Construction

[0016]FIGS. 1 and 2 are perspective and top views of an applicator 100 in accordance with the invention Applicator 100 comprises a generally elongate body 102 having a handle portion 104 and a dispenser portion 106. Handle portion 104 includes a reservoir 108 defined at its top and bottom ends by flexible walls 110 and 112, respectively. Reservoir 108 is adapted to contain a fluid, such as medical cyanoacrylate. A framing structure 114 radially surrounds reservoir 108 and provides rigidity to the applicator 100. Suitable materials for the reservoir 108 and framing structure 114 include high density polyethylene (HDPE), polyvinylchloride, polypropylene, polycarbonate, polytetrafluoroethylene (PTFE), FEP, and the like. When the fluid is medical cyanoacrylate, compatible materials such as HDPE and polypropylene could be used.

[0017] Dispenser portion 106 of applicator 100 comprises a pad 116, made from foam or other porous material, such as cotton, polyolefin foam, polyester polyuretha...

Abstract

An applicator has a reservoir adapted to contain a fluid and a pad in fluid communication with the reservoir. A tab serves to seal the fluid reservoir at a breakable connection, with breaking of the breakable connection allowing passage of fluid from the reservoir into the pad. The tab may be removable, or it may be embedded in the tab. Fluids with which use of the applicator is contemplated include sterilizable fluids for therapeutic applications to tissue, including topical liquids such as tissue adhesives for surgical applications, coatings and sealants. One candidate fluid is a cyanoacrylate prepolymer.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention is directed to single-use disposable applicators for the application of liquids. More particularly, it is directed to improved applicators and methods for applying adhesives, sealants and coatings, and particularly for the application of medical adhesives, sealants and coatings. [0003] 2. Description of the Related Art [0004] Disposable containers for small to medium quantities of reactive or medicated liquids tend to be based on a few concepts: bottles screw caps; mechanical rupture of a thin section of a container, such as in a glass ampoule with a fragile neck, plastic eye lubricant container with a twist off tab, Unicep=198 dispenser with a snip off point, and like. Where application or spreading of the liquid is also required, there are fewer options available, such as fragile breakage of a glass container inside an applicator, or mechanical piercing of a film of foil seal to release the contained...
